Fertilisers contain minerals such as nitrogen, potassium and phosphorus, which help plants to grow. Fertilisers increase crop yields but cause the problem of 'eutrophication' when they're washed by rainwater into rivers and lakes.Most chemical fertilisers are made by the reaction of an acid with an alkali.hey're minerals, which must first dissolve in water so that plants can absorb them through their roots. Fertilisers provide plants with the essential chemical elements needed for growth particularly nitrogen, phosphorus and potassium.
Pet Poison Helpline. Fertilizers. Most fertilizers contain varying amounts of nitrogen, phosphorus and potassium (potash) as indicated by the three numbers on the packaging (i.e., 30-10-10). They may also contain iron, copper, zinc, cobalt, boron, manganese and molybdenum, some of which may be toxic in large concentrations. Additionally, fertilizers may also contain herbicides, pesticides, and fungicides which increases the risk of poisoning. While small ingestions of fertilizer may only result in mild stomach upset, larger ingestions can result in severe poisoning from the iron, nitrogen and other chemicals.
